Polyanionic cellulose (PAC) is a multifunctional polymer, among which PAC viscosifier and fluid loss control agent are often used in oil and gas extraction. As a water-soluble derivative of cellulose, polyanionic cellulose (PAC) is very effective in controlling fluid loss and increasing drilling fluid viscosity.

The additives used in the traditional oil and gas extraction process have low solubility, large additive dosage and high loss. However, PAC has good solubility in both fresh water and salt water, which can reduce the loss during the mining process.

At the same time, high water solubility also allows PAC viscosifiers and fluid loss control agents to be effectively used in various drilling environments from offshore deepwater wells to land-based drilling operations. The effectiveness of the polyanionic cellulose additive is further enhanced by its high resistance to contamination by salts and other contaminants commonly found in drilling fluids.

Polyanionic additives have more functions in the drilling process. For example, PAC drilling fluid additives can cool the drill bit, clean the well wall, and transport the drill bit. In addition, polyanionic cellulose can also be used in conjunction with other additives to enhance its anti-pollution and salt resistance.
